Abstract
A low dropout (LDO) regulator includes a voltage regulation loop for providing an output voltage to an output terminal, where the output voltage is proportional to a reference voltage. The voltage regulation loop includes a current bias input for receiving a bias current. The LDO regulator also includes a bias current control circuit for providing the bias current at a first value when the reference voltage is greater than a feedback voltage and at a second value higher than the first value when the reference voltage is less than the feedback voltage.
